Default Gateway does not work

[Armin@netPI]

There is a little progress in my notebook setup and Raspberry Pi.

I was specifically adding the gateway in the routing table using the command

Code:

ip route add 169.254.100.97 dev eth0

With this additional entry my Raspberry Pi is now sending out the ping command as intended. I was able to see in it Wireshark

... and I see with Wireshark my notebook sending out the same ping command out to the internet and I see the replay back to it too

... what I don't see is that my notebook routes back the ping reply back to my Raspberry Pi.

So there is still something missing.
